Models equipped with the Quick Number Change feature are being released one after another [Feature Introduction].

Easily change the memory number with just key operations. No stress, it can be changed in a few seconds!

The Keylex series is continuously launching models equipped with the "Quick Number Change Function"! The "Quick Number Change Function" allows for the deletion and registration of memory numbers using the included key operation. The method of changing is very simple: to delete a number, just insert the key into the cylinder and turn it in the RESET direction; to register a number, press the desired number button and then turn the key in the SET direction. This eliminates the hassle of having to remove the Keylex unit from the door every time a change is made! It is recommended for places like hotels and vacation rentals where numbers are changed regularly. Additionally, in rental housing, changing the number when tenants change eliminates the need to replace the cylinder, thereby reducing costs. The method for changing memory numbers is also introduced in a video on the official Nagasawa Seisakusho YouTube channel!
